Know what you’re replacing.
A slow crank, clicking, or a "battery saver active" message usually means your F-150 needs a new battery. On the 13th-gen F-150 the battery is under the hood and the swap takes about 30 minutes. Trucks with Auto Start-Stop need an AGM battery.

A little preparation first.
- Check the label on your current battery and match the group size and type (AGM vs flooded).
- Some trucks have a second (auxiliary) battery — this guide covers the main one.
- Engine off, key away from the cab, glasses and gloves on.
One step at a time.
2Disconnect the negative (–) terminal
Loosen the black terminal nut and lift the cable off. On trucks with a battery monitoring sensor, disconnect at the clamp, not the sensor plug.
3Disconnect positive and remove the hold-down
Remove the red terminal, then unbolt the hold-down bar with a socket and extension.
4Lift out the old battery
Truck batteries are heavy (40–55 lb). Lift straight up with both hands.
5Install the new battery
Seat it the same way, refit the hold-down, connect positive first, negative last, and tighten both clamps.
